In a small saucepan, bring the water and a pinch of salt to a boil.
Whisk in the grits, reduce heat to low, cover, and simmer for 15-20 minutes until creamy, stirring occasionally.
Stir 1 teaspoon of ghee into the finished grits and keep warm.
While grits cook, pat the shrimp dry and toss with Cajun seasoning, salt, and pepper in a bowl.
Heat the remaining 1 teaspoon of ghee in a large skillet over medium-high heat.
Add the diced red bell pepper and sauté for 3 minutes until slightly softened.
Add the minced garlic and shrimp to the skillet, cooking for 2-3 minutes per side until the shrimp are pink and opaque.
Spoon the creamy grits into a bowl and top with the sautéed Cajun shrimp and peppers.
Garnish with fresh sliced green onions and serve immediately.
